However, by moving the process chambers 66 and 68 to the exposure position at the same time, the working efficiency is further increased. 3 and 4, when one of the process chambers (the left process chamber 66 in Figs. 3 and 4) is opened, (The right process chamber 68 in Figs. 3 and 4) is the position between the one process chamber and the main chamber 64, and the other process chamber It is possible to secure a sufficiently large working space for both of the process chambers 66 and 68 by moving them to an intermediate position where they do not overlap (that is, they do not interfere with each other).

For example, in the arrangement shown in Figs. 3 and 4, with respect to the right process chamber 68 at the intermediate position, the worker can access from the left side of the apparatus in the path indicated by the broken line L1, The target 85 and the like can be carried in and out along the same route by using the hoist 142 installed in the hoist 142. [ This carry-in / take-out can be transferred, for example, between a remote location of the film forming apparatus and a stile 146 shown in FIG. 4 by using a truck, not shown. In the same way as the above, a process chamber which is separated from the main chamber 64 to the position where it completely passes the left process chamber 66, that is, the right process chamber 68, It is possible. Specifically, in the state shown in Fig. 4, for example, the worker can access the left process chamber 66 in the path indicated by the broken line L3. It is also possible to carry in and out the film formation mask 203 or the like through the opening 80 of the main chamber 64 opened by the movement of the process chambers 66 and 68 in the path indicated by the broken line L2 in Fig. . In addition, by disposing the left and right process chambers 66 and 68 opposite to the arrangement shown in Fig. 4, the mask 203 and the like on the opposite side in the path indicated by the broken line L4 can be carried in and out. It is also possible to carry out the film-forming mask 203 from the front side of the apparatus, for example, in a route indicated by broken lines L5 and L6.

The present invention is not limited to the embodiments described above.

For example, the directions of movement of the process chambers 66 and 68 with respect to the forward and backward directions may be set to be opposite to each other. For example, the guide rails 110 may be installed to move the left side process chamber 66 to the front side and the right side process chamber 68 to the front side. However, by unifying the directions of movement of the two process chambers 66 and 68, for example, setting them to the rear side as shown in Figs. 3 and 4, it is possible to drastically reduce the occupied space of the entire apparatus , And also makes it possible to further improve the efficiency of operations such as maintenance on each of the process chambers 66 and 68.

However, this retreat position is not limited to the process chamber in which the process chamber and the film- It is sufficient if the position is slightly spaced apart from the normal position to such an extent as to avoid the interference of the rollers and the like. Therefore, it is possible to arrange the upstream side and the downstream side units at positions adjacent to the left and right sides of the film formation unit. Further, by moving the process chamber from the retracted position to the exposed position largely in the longitudinal direction, it is possible to perform operations such as maintenance on both the process chamber and the main chamber left without hindrance.
